iOS 7 or iPhone 6: Improvements that I would like to see

Apple Computer is going to release iOS 7 for the iPhone and iPad this fall. They are also expected to release a new iPhone this fall (either a 5S or 6). I currently am using an iPhone 4S running iOS 6. Here are some improvements that I would like to see in the new operating system and/or phone:

• The date on the Calendar app changes every day. I want the Weather app to show the correct current temperature (now it always shows 73º) and the Clock app to show the correct local time (now it always shows 10:15). I understand that changing the Weather and Clock apps could use up the battery faster but I'm confident that Apple can figure out how to accomplish this without wasting battery power (mostly by not updating when I can't see the display).
• I want to select the default browser (I prefer Chrome to Safari) and the default maps (Google Maps is still more accurate than Apple's Maps app).
• Many apps (such as Facebook and LinkedIn) include a browser within the app. When you're done with a page in the browser, you tap the back arrow at the top of the screen to go back to the app. Others (sorry, I can't come up with an example) use Safari to display web pages. However, in Safari, there is no back arrow to go back to the app; you have to leave Safari and try to remember which app you were in. The link to Safari should have a back arrow to take you back to the app.
• Speaking of back arrows, why is Safari's at the bottom of the screen instead of the top like every other app?
• Here's one that has to be fixed in hardware: There are two speakers at the bottom of the phone. That's great for portrait mode, but when I rotate the phone to look at a video in landscape mode, the way it was designed to be seen, all of the sound comes out of the left side. There needs to be one or two speakers on the top as well (the second added speaker is for people who rotate the other way).
• When I go into a restaurant with free Internet through wi-fi my phone connects to it with a minimum amount of hassle. So far, so good. Sometimes, the wi-fi is dog slow and I can't do anything with it. Currently, I have to turn the wi-fi off so I can get the faster speed of 3G (yes, it does happen that 3G is faster). I want the phone to select the faster of wi-fi or 3G (4G for later models) for my connection in this situation.
• I would like two improvements to the Contacts list in the Phone app: The ability to rearrange the sequence of phone numbers in a contact and the ability to display the company name in place of the phone number type. For example, if I look at my recent calls, I see that Sam at "work" called me recently. I would prefer that the entry say Sam at Acme Staffing Service (not the real company) instead. I usually don't care what number within the contact he used to call me.

That's all the changes I want today. Let's see how many of these get fixed in the next release of software and hardware.

Updated July 21 to fix grammar and formatting.
